(2x+xy^2)dx+(2y+x^2*y)dy=0
求齐次方程y(x^2-xy+y^2)dx+x(x^2-xy+y^2)dy=0
(2x+xy^2)dx+(2y+x^2*y)dy=0
1.求(xy^2+x)dx+(xy^2-y)dy=0的通解
微分方程(xy-y)dy-(x+xy^2)dx=0的通解是?
求齐次方程y(x^2-xy+y^2)dx+x(x^2-xy+y^2)dy=0.
求解微分方程(xy^2+x)dx+(y-x^2y)dy=0,y(2)=1的通解
设sin(xy)-x^2y=0,求dy/dx,求导什么的都要疯了!
求解(x^3+y^3)dx-3xy^2dy=0的通解
求解微分方程 x^2*dy/dx=xy-y^2
dy/dx=1+x+y^2+xy^2
求齐次微分方程dy/dx=y^2/xy-x^2
dy/dx=xy/x^2-y^2
